Brief summary

Gallbladder management in bariatric surgery is controversially discussed. While some surgeons advocate routine prophylactic cholecystectomy (CCE) during Roux-en-Y gastric bypass (RYGB) others advocate CCE only in patients with pathological gallbladder findings. The aim of this study was to evaluate the necessity of prophylactic CCE in patients receiving a laparoscopic RYGB.
